Constructor Details

#initialize(opts = {}) ⇒ HTMLLegacy

Initialize with options.

If :inline_theme is given, then instead of rendering the tokens as tags with CSS classes, the styles according to the given theme will be inlined in "style" attributes. This is useful for formats in which stylesheets are not available.

Content will be wrapped in a tag (div if tableized, pre if not) with the given :css_class unless :wrap is set to false.

Parameters:

  • opts (Hash) (defaults to: {}) —

    a customizable set of options

Options Hash (opts):

  • :css_class (String) — default: 'highlight'
  • :line_numbers (true/false) — default: false
  • :inline_theme (Rouge::CSSTheme) — default: nil
  • :wrap (true/false) — default: true
